列表视图项之间的巨大距离

Question

我有一个权重总和为 4 的列表视图。包含图像后，我有很大的填充，但我清除了所有边距和填充。通过适配器从 MainActivity 接收所有数据。下面有屏幕截图和代码。感谢观看和帮助。

    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="Пн, сегодня"
        android:id="@+id/title"
        android:layout_weight="1"
        android:layout_gravity="center_vertical"
        android:gravity="center" />

    <ImageView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:id="@+id/icon"
        android:layout_weight="1"
        android:src="@drawable/ic_cloud_queue_24dp"
        android:layout_gravity="center_vertical" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="+17"
        android:id="@+id/genre"
        android:layout_weight="1"
        android:gravity="center"
        android:layout_gravity="center_vertical" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="+9"
        android:id="@+id/year"
        android:layout_weight="1"
        android:gravity="center"
        android:layout_gravity="center_vertical" />

</LinearLayout>

Answer 1

尝试使用此代码。

Changes i have made is added Linear Layout inside Relative Layout with match_parent as Height and Width. Because Linear Layout childs containing match_parent as height so that will affect the list items. That's why i have added new Root Layout and defined all childs as OP.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/ll1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="4">

        <TextView
            android:id="@+id/title"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="Пн, сегодня"
            android:textAppearance="?android:attr/textAppearanceSmall" />

        <ImageView
            android:id="@+id/icon"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:src="@drawable/ic_dashboard" />

        <TextView
            android:id="@+id/genre"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="+17"
            android:textAppearance="?android:attr/textAppearanceSmall" />

        <TextView
            android:id="@+id/year"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="+9"
            android:textAppearance="?android:attr/textAppearanceSmall" />

    </LinearLayout>

</RelativeLayout>

Answer 2

LinearLayout 这四个元素的高度为 wrap_content，这基本上意味着使它成为 children 的高度。但是所有 4 children 的高度都是 match_parent，这表示刚好适合我的 parent。所以这不是很兼容。我会做的是也给所有 4 children 高度 wrap_content，或者更好的是给 LinearLayout 一个固定的 layout_height
